BcG729 is an implementation of both encoder and decoder of the ITU G729 speech codec. The library written in C 99 is fully portable and can be executed on many platforms including both ARM and x86 processors. It supports concurrent channels encoding and decoding for multi call application such as conferencing.

oRTP is a C library implementing the RTP protocol. It implements the RFC 3550 standard.

Liblinphone is a high-level SIP library integrating all calling and instant messaging features into an unified easy-to-use API. It is the cross-platform VoIP library on which the Linphone application is based on, and that anyone can use to add audio and video calls or instant messaging capabilities to an application.

LIME is an encryption library for one-to-one and group instant messaging, allowing users to exchange messages privately and asynchronously. It supports multiple devices per user and multiple users per device.

Belle-sip is a modern library implementing SIP transport, transaction and dialog layers. It is written in C, with an object-oriented API. It also comprises a simple HTTP/HTTPS client implementation.

MSAMR is a plugin of MediaStreamer, adding support for AMR codec. It is based on the opencore-amr implementation.

Linphone is a SIP softphone for voice and video over IP calling (VoIP) and instant messaging. Amongst its features are:

• High Definition (HD) audio and video calls

• Multiple call management (pause and resume)

• Call transfer

• Audio conferencing (merge calls into a conference call)

• Call recording and replay (audio only)

• Instant Messaging with message delivery status (IMDN)

• Picture and file sharing

• Echo cancellation

• Secure user authentication using TLS client certificates

• SRTP, zRTP and SRTP-DTLS voice and video encryption

• Telephone tone (DTMF) support using SIP INFO or RFC 4733

• Audio codecs: opus, speex, g711, g729, gsm, iLBC, g722, SILK, etc.

• Video codecs: VP8, H.264 and H.265 with resolutions up to 1080P, MPEG4

Belcard is a C++ library to manipulate VCard standard format.

Mediastreamer2 is a powerful and lightweight streaming engine for telephony applications. This media processing and streaming toolkit is responsible for receiving and sending all multimedia streams in Linphone, including media capture, encoding and decoding, and rendering.

Belr is Belledonne Communications' language recognition library, written in C++11. It parses text inputs formatted according to a language defined by an ABNF grammar, such as the protocols standardized at IETF.

MSSILK is a plugin of MediaStreamer, adding support for AMR codec. It is based on the Skype's SILK implementation.

MsOpenH264 is an H.264 encoder/decoder plugin for mediastreamer2 based on the openh264 library.

BcToolBox is an utilities library used by Belledonne Communications software like belle-sip, mediastreamer2 and linphone.

BcMatroska is a free and open standard multi-media container format. It can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. This project provides a convenient distribution of the Matroska multimedia container format.

Prevents shock damage to the internal spinning hard drive(s) of some HP and Dell laptops. When sudden movement is detected, all input/output operations on the drive are suspended and its heads are parked on the ramp, where they are less likely to cause damage to the spinning disc. Requires a drive that supports the ATA/ATAPI-7 IDLE IMMEDIATE command with unload feature, and a laptop with an accelerometer. It has no effect on SSDs.

acpilight is a backward-compatibile replacement for xbacklight that uses the ACPI interface to set the display brightness. On modern laptops acpilight can control both display and keyboard backlight uniformly on either X11, the console or Wayland.

jmtpfs uses FUSE to provide access to data over MTP. Unprivileged users can mount the MTP device as a file system.

lshw (Hardware Lister) is a small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, and more on DMI-capable x86 or EFI (IA-64) systems and on some PowerPC machines (PowerMac G4 is known to work).

OpenFabrics Interfaces (OFI) is a framework focused on exporting fabric communication services to applications. OFI is best described as a collection of libraries and applications used to export fabric services. The key components of OFI are: application interfaces, provider libraries, kernel services, daemons, and test applications.

Libfabric is a core component of OFI. It is the library that defines and exports the user-space API of OFI, and is typically the only software that applications deal with directly. It works in conjunction with provider libraries, which are often integrated directly into libfabric.
